Answer : Scheduling strategies
A typical scheduling strategy used in Argentinian radio and television is called “pase” (Spanish for a “pass” as in a player passing the ball to another player of the same team). A few minutes before the end of a live broadcast show, followed by another live broadcast show, people from both programmes will share some air time together.
This may be used for people from the starting programme to anticipate its contents of the day, or to participate in an ongoing discussion in the previous show, or simply for an entirely independent debate or chat that will not be furthered after the “pase”. On the radio, where newscasts are usually broadcast every thirty minutes, often in coincidence with the end of a show, the “pase” may take some minutes before the news, and sometimes some minutes afterwards, too.
